Abstract
In addition, at the northern part of this so-called Gaenserndorf terrace, high-resolution digital terrain models based on LIDAR measurements show landforms comparable with relief features resulting from permafrost degradation. Large elongated and clam-shaped depressions are interpreted as basins of former thermokarst lakes. Current dry valleys are interpreted as the Pleistocene drainages of the terrace surface. The cryogenic morphology is preserved only in the elevated parts of the terrace and therefore in the footwall of the bounding normal faults. In contrast, Quaternary basins of the hanging wall are filled with up to 40 m thick Pleistocene and Holocene growth strata. Therefore, most characteristics of the recent geomorphology can be interpreted as a result of overlapping neotectonic processes and permafrost degeneration during the Pleistocene.
